Glucosamine/glucosaminide N-acetyltransferase or GlmA catalyzes the transfer of an acetyl group from acetyl CoA to the primary amino group of glucosamine. The enzyme from Clostridium acetobutylicum is thought to be involved in cell wall rescue. In addition to glucosamine, GlmA has been shown to function on di- and trisaccharides of glucosamine as well. Here we present a structural and kinetic a...

The interaction between azurin from Pseudomonas aeruginosa and Ag(I), Cu(II), Hg(II), was investigated as a function of protein state, i.e. apo-, reduced and oxidised azurin. Two different metal binding sites, characterized by two different spectroscopic absorbancies, were detected: one is accessible to Ag(I) and Cu(II) but not to Hg(II); the other one binds Ag(I) and Hg(II) but not copper. Whe...

The purpose of the paper is an investigation of compactness properties of a family of solutions of a BGK-type model for near equilibrium kinetic densities for the system of the Euler equations for isentropic flows. 0.

Investigation of transfer processes in dense weakly or fully ionized many-component gases is topical in view of construction and improvement of new gaseous lasers, plasmo-chemical reactors for ozone synthesis, and air cleaning of both nitrogen and carbon oxides and chlorine compounds. A study and calculation of transfer coefficients taking into account the interparticle interaction nature is on...

BACKGROUND Occurrence of psoriasis has been found to be strongly genetically controlled in Northern European and U.S. twin and family studies. OBJECTIVE Our purpose was to assess cumulative incidence and heritability of psoriasis in the Australian population. METHODS Australian twins reporting psoriasis on a screening questionnaire received from 3808 pairs were mailed a detailed instrument ...

While multiple studies have shown that a woman’s control over land is positively associated with bargaining power outcomes, few have succeeded in highlighting successful methods for increasing this control. We report on a policy experiment in an unplanned settlement in Dar es Salaam, Tanzania, that provided access to formal land titles to informal settlers at randomized prices, with additional ...

OBJECTIVES To assess whether public health nurses adhered to Dutch guidelines for tuberculosis contact investigations and to explore which factors influenced the process of identifying contacts, prioritizing contacts for testing and scaling up a contact investigation. METHODS A multiple-case study (2010-2012) compared the contact investigation guidelines as recommended with their use in pract...

OBJECTIVE Area 7 of the autonomous region of Madrid has one of the highest incidences of tuberculosis (23/100,000 population per year 2004). This study aimed to identify tuberculosis control in this area. METHODS A descriptive study of tuberculosis cases diagnosed in area 7 from January 1, 1999 to December 31, 2004 was carried out by analyzing the incidence of tuberculosis and the management ...
